BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to preparation and use of biphenyl acetate, and more particularly to a preparation and use of biphenyl acetic ammonia butantriol salt.

2. Description of Related Arts

In 1993, biphenyl acetic acid is commonly used as a medicine for reducing inflammation and relieving pain in Japan and Italy. The biphenyl acetic acid is used to provide analgesia and anti-inflammatory effect related tometaboly arthritis, omarthritis, tenosynovitis, muscle pain and cartilage tissue injury. In addition, it is also used for reducing traumatic swelling and pain. Because of its insolubility in water, biphenyl acetate can only be used for traumatic medicine. This property restricts the application of this medicine dramatically.

In Japan, biphenyl ethyl acetate has been used for injecting emulsion (insoluble in water) for reducing clinical pain of a living object. However, the manufacture of this medication has recalled this type of emulsion recently because it is discovered that the emulsion may cause a shock phenomenon to the living object. Further clinical studies found that allergy is the major cause of the shock phenomenon and the soy phosphatidoo acting as the coemulsifier of the injecting emulsion acts may be one of the allergen. Therefore, the biphenyl ethyl acetate which is manufactured in an emulsion form has the drawbacks of very low stability, involving complicated preparation process and technique and being unsafe owing to the macromolecular structure of the coemulsifier. In other words, in view of the functional group of biphenyl acetic acid, there is no solution provided to make use of this functional group for preparation of injection solution or the like which is stable in structure and safe for administration as injection to a living object. It is worth mentioning that the injecting emulsion contains macromolecular protein which may not only impose toxic effect on liver but also cause allergy to the living object, therefore imposing safety issue when used in living object.

SUMMARY OF THE PRESENT INVENTION

An object of the present invention is to provide a new kind of biphenyl acetate, which is biphenyl acetic ammonia butantriol salt. The biphenyl acetic ammonia butantriol salt has the following chemical structure.

Its molecular structure is C₁₈H₂₃NO₅, and its molecular weight is 333.14.

Another object of the present invention is to provide a manufacturing method of biphenyl acetic ammonia butantriol salt. This method is to react biphenyl phenylacetic acid with ammonia butantriol in organic solvent, and then generate biphenyl acetic ammonia butantriol salt. The reaction formula is below:

In the method above, it is available to add biphenyl phenylacetic acid with ammonia butantriol at the same time in organic solvent, or add biphenyl phenylacetic acid first. It is also available to add ammonia butantriol first in organic solvent, and then react with biphenyl phenylacetic acid to generate biphenyl acetic ammonia butantriol salt. In order to increase recovery rate, the ratio of biphenyl phenylacetic acid and ammonia butantriol should be 1:1. As for organic solvent, this organic solvent should have the ability to dissolve phenyl acetic acid, such as alcohol and benzene, and especially chose methanol, anhydrous ethanol, acetone, and n-butanol, benzyl and benzene. In the method above, there are not any special requirement for temperature and time. The normal reaction temperature is 0-80° C., but it prefers to set the temperature at 50-70° C. The reaction time is 0.5-2 hours.

The method also includes the procedure of the purification of biphenyl acetic ammonia butantriol salt. There are variety purification methods that we can use today, and here are two classic purification method: the first one is to evaporate solvent, and then generate the white powder after the reaction. Further, the procedure is to dry the white powder in vacuum, and then generate biphenyl acetic ammonia butantriol salt. The other method is to cool down the solvent below 0° C., and then generate crystallization. Consequently, we dry the crystallization in vacuum to produce biphenyl acetic ammonia butantriol salt. The second method is the best way to use, because it can get the better compound's purity and crystal analgesic.

According to the above manufacturing method, the yield of biphenyl acetic ammonia butantriol salt is 85.6-96%, and the purity is 99.2-99.8%. Further, the melting point is 162-163° C.

Another object of the present invention is to provide the pharmaceutics application of biphenyl acetic ammonia butantriol salt. As for the research, this biphenyl acetic ammonia butantriol salt has anti-inflammatory, analgesic, and antipyretic. Accordingly, the subject matter of the present invention is the active compound of biphenyl acetic ammonia butantriol salt.

If the purpose require, we can add one or more kinds of accepting carrier in this medicine, including diluting agent, excipient, extender, adhesive, moistening agent, disintegrating agent, absorbefacient, surfactant, adsorption agent, and lubricant. This medicine also can add scenting agent, sweetening agent and so on.

This medicine can be manufactured as injection (injective liquid, injective cool powder, and injective aseptic needle), tablet, powder, pill, capsule, oral liquid, cream, and so on. These above kinds of medicines all can be manufactured in terms of the normal order in pharmaceutical field. The amount of taking this biphenyl acetic ammonia butantriol salt medicine is 0.8-3.6 mg/kg/days.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The embodiment of the present invention as shown and described below is exemplary only and not intended to be limiting. Therefore, this invention includes all modifications or any combination encompassed within the spirit and scope of the followings.

The following description illustrates a preparation of biphenyl acetic ammonia butantriol salt according to a first preferred embodiment of the present invention.

21.2 g (0.1 ml) of Biphenyl acetate and 210 ml of methanol are added into a dry and clean 250 ml three opening round bottom crucible bottle. Stir and heat the mixture to 60° C. until the mixture is totally dissolved. Add ammonia butantriol into the mixture solution until the solution is in a clarified transparent manner. Stir the solution for one hour and make TLC fully reacting with the solution. (eluent: DMF-acetic ester 2:1). Set the end point when the raw material biphenyl acetate is totally reacted with another reactants. Cool down to −5° C. for 5 hours and get huge amount of white crystal. Remove chloride and put the solution into vacuum dry machine at 80° C. Finally, we can get the biphenyl acetic ammonia butantriol salt in a white crystal manner. The melting point thereof is between 162 and 163° C. The yield is 91.6%. The theoretical value of element analysis is C: 64.9%, H: 6.9%, N: 4.2%, O: 24%. The actual value of element analysis is C: 64.1%, H: 7.3%, N: 3.6%, O: 25%).

FIG. 1 shows the ¹HNMR spectroscopy analysis of biphenyl acetic ammonia butantriol salt.

There are eight hydrogen peaks signal in the ¹HNMR spectroscopy of the biphenyl acetate in the solvent of DMSO-d6. According to the chemical shift in HNMR spectroscopy, all peaks' chemical shift (δ) below 4 ppm are H signal of saturated carbon, and the total sum of peaks are 14. Therefore, if δ value is smaller than 6 ppm, there are all H signal of aromatic ring, and the total number of these peaks is 9. At δ=3.35 ppm, the 2H single hydrogen peak cab be determined as an isolated CH2 group. In the structure of biphenyl acetate, the carbon No. 13 which connects with benzene and COO— in CH2 does not accept the coupling of other hydrogen's core. At δ=3.43 ppm, the 3H single peak cab be determined as three equal value isolated CH2 group. In the structure of biphenyl acetate, carbon NOs. 18, 19, 20 all connect with the carbon No. 17 of the CH2, and these three CH2 are equal values. Because of these three CH2 does not accept the coupling and have the equal value, it reveals single peak signal. The wide peak at δ=3.43 ppm can be determined as three OH group and a protonation's NH3+, because these active H probably combine with the water which is in the solvent, it reveals a wider peak. The integral value cannot explain the real number of these active H, because there is water in this solvent. There are four splitting signal groups in the low magnetic field, and according to these peaks' area it only can be known that there are 3, 2, 2, 2, H from high to low magnetic field. Further, there are only three left groups which can be clarify their peak shape, so they can be clarified as two duplicate and one triple peaks. In addition, it can be explained that there are H on the benzene due to their chemical shift, so two duplicate peaks near 8.0 Hz which named ad peak No. 7 and No. 8 can indicate as two positions. One position is on a side of benzene which has H, and the other is a side of benzene which does not have H but have other substituted group. The two duplicate peaks can be explained as four H in the structure of biphenyl acetate which are H2/H6, H3/H5, and H8/H12. Furthermore, the triple peaks nearby 7.6 Hz can be explained as positions that those benzenes have H on their both side, and there are H9, H10, and H11 in this molecular structure.

IR spectroscopy analysis of biphenyl acetic ammonia butantriol salt is shown in FIG. 2.

(1) It can be determined the structure of this molecule has amine salts of carboxylic acids, if there is a wide and strong COO— stretching vibration peak at 1560.13 cm⁻¹, and wide, strong, and scattered NH3+ characteristic peak at the region of 2927.41-2113.60 cm⁻¹. The COO— and NH3+ form a COO—. NH3+ free monomer molecular structure, and COO— and NH3+ also easily form hydrogen bonds between dimmer to polymer. In addition, the stretching vibration frequency region of NH3+ and OH of CH2—OH reveal at 2927.41-2113.60 cm⁻¹, and then form multiple, overlapping, scattered, and strong peaks.

(2) The stretching vibration wide strong peak of OH is at 3214.94 cm⁻¹. The other deformed vibrations about OH group (δ OH) are at 1423.21 cm⁻¹ and 1278.57 cm⁻¹, and further a flat shaking vibration is at about 690.39 cm⁻¹ (rOH). It can be explained that the wide, strong, and stretching vibration peak at 1083.80 cm⁻¹ is C—O (vC—O), so it also can declare that OH directly connect with CH2.

(3) The series spectrum peaks at 2987˜2896 cm⁻¹, which are determined there are saturated carbon hydrogen group in this molecular structure, are both the asymmetric and symmetric stretching vibration group, such as CH3 and CH2. At the same time, the deformed absorbing vibration of CH3 and CH2 reveal at the region of 1467˜1367 cm⁻¹ Even though, it can be reasoned from NMR spectrum that this compound does not contain methyl, there are some disrupted peaks near by 2965±cm−¹ and 1375±cm⁻¹ from IR, so it cannot be clarify that this compound does not include methyl.

(4) At 3100˜2980 cm⁻¹, there are a series of peaks that can be declared this molecular structure has unsaturated hydrocarbon group, such as aromatic ring, benzene ring, and alkene structure. At 1650˜1423 cm⁻¹, there are many unsaturated group that can be determined as C═C and C═N. At 1201˜977 cm⁻¹, it can be determined that has an internal bending vibration (β) of ═CH group in benzene. At 738.6 and 690.39 cm⁻¹, it can be determined that has two outer bending strong vibration peaks of monosubstituted benzene ring (γ). At the region of 2000-1666 cm⁻¹, a series' peaks in this region are the same as the overlapping and combined of a monosubstituted benzene ring and a p-disubstituted benzene ring.

(5) There is stretching vibration of amine salt's C—N bond which reveals at 1045.2 cm⁻¹, and further, there is an outer bending vibration (γ) of NH3+ reveals at 605.5 cm⁻¹.

Mass spectroscopy analysis of biphenyl acetic ammonia butantriol salt is shown in FIG. 3.

The positive molecular ion (C₁₈H₂₃NO₅+.) of the biphenyl acetate molecule are examined that its charge-mass ratio (m/z) is 332.2 and relative abundance is 20. Therefore, the ratio value is 333.16 for calculating with accurate mass theory, because the low measuring accuracy of low resolution mass spectrometer generates mass relative error which is 5×10−4. In the theory, the calculating value of C₁₈H₂₂NO₅+ ion mass fragment is 332.15 m/z, so it only has 0.6×10−4 relative error.

The structure of the biphenyl acetic ammonia butantriol salt is I, and the purification is 99.5%.
